Modern casino slot games are controlled by computer chips and software, and the win percentages are preprogrammed into the game software.
Casino slot machines have Random Number Generators that are ceaselessly generating combos, even when the slot machine game is not being played.
Running in unison with the random # generator of the casino slot machine is the pay out %.
The pay out percent controls just how much the slot machine will pay out, for eg the pay % could be 90%, meaning the slot machine will pay ninety per cent of all the bets played, and the casino will then get to keep 10 per cent.
This really does not mean that each time you bet ten credits you will receive 9 in return – where’s the fun … thrill in that? Instead, the casino slot machine game just won’t pay out for a bit, and then suddenly start up a hot streak and you might hit a big pot prize.
The pay out %s most likely will vary between the different games and just a few of the extremely famous casinos, like Golden Online Casino, which hands out a pay out of up to 95 %!
Hence, in essence, the slot machine game takes all the currency played into it and pays it out to a couple of chosen winners. The casino only gets to keep a averagely tiny per cent of all the wagers placed.
The casino slot machine software controls every single part of the machine, from the dazzling lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is produced by the RNG which corresponds to the pictures on the reel.
